88

Of course, the material for the resistive element 208 may be conventional materials such as copper, iron, and the like which have a positive temperature coefficient of resistance. Preferably, the resistive element 208 comprises a material having a negative temperature coefficient of resistance such as graphite, germanium, silicon, and the like. In addition to substantially reducing in rush current, the negative temperature coefficient of resistance elements such as graphite 810 also give off more heat once the current has flowed for some period.
